Abstract

The invention relates to a marine tank ventilation system. The first ventilation box and the second ventilation box are both arranged in the deck cabin of the fore floor of the ship. The partition plate of the cavity, the first lubricating oil vent pipe, the second lubricating oil vent pipe and the first engine inner cavity vent pipe are connected with the upper cavity of the first vent box provided with the first vent port, and the first fuel vent pipe is connected with the first vent box. The lower chamber of the vent box with the second vent is connected, the third oil vent pipe, the fourth oil vent pipe and the second engine inner cavity vent pipe are connected to the upper chamber of the second vent box with the third vent port The cavity is connected, and the second fuel ventilation pipe is connected with the lower cavity of the second ventilation box provided with the fourth ventilation port. The invention can centrally arrange the venting outlet of the ship's tank, avoid the spread of oil in all directions, collect oil and gas in a concentrated manner, avoid the mutual channeling of different types of oil and gas, and reduce the occupation of deck space.

Description

technical field [0001] The invention relates to the technical field of ship pipelines, in particular to a ship liquid tank ventilation system. Background technique [0002] The ship pipeline system is an indispensable part of the ship. The ship tank ventilation pipeline is a part of the ship pipeline system. The ship tank ventilation generally needs to pass through the deck surface to lead to the atmosphere. For fuel oil and lubricating oil, the deck is breathable and contains oil mist. If it is not handled properly, it will become a source of pollution to the ship and the marine environment. The spread of oil will pollute the ship and affect the safety of the crew. For this reason, the ventilation pipes for fuel and lubricating oil are usually directly led above the upper deck, and the oil tank is made of steel plates. There is inevitably dirty oil around the oil tank, and the oil in the oil tank needs to be cleaned regularly; even if the closed oil tank is collected throug...
